Application filed November 3, 1 1a. Serial No. 129,376.

To all whom it may concern."

' Be it known that I, HAROLD C. HA'rc -rL,

a citizen of the United States, residing at Nacogdoches, in the countyof Nacogdoches and State of Texas, have invented certain new and usefulImprovementsin Awning- Locks, of which the following is a specifiparticularly, to a novel locking attachment therefor.

The invention has for its principal object to provide a lockingattachment for roll awnings or curtains and the like, whereby, the freeend of thesame when in unrolled or lowered position, will be engaged andretained in a fixed position and will not be accessible from the outerside thereof, thereby, providing a device especially adapted for useupon sleeping po ches and other similar places where it is desirable toprovide means which will prevent intruders from gaining entrance.

As an object of equal importance, the in vention also aims to provide alocking device which can be readily attached to a porch or otherconstruction, without materially altering the same or detracting fromthe effect of the design thereof.

Among other aims and objects of the invention may be recited, theprovision of an attachment of the character mentioned with a view tocompactness, and in which the number of parts are few, the constructionsimple.

Other and further improvements and novel details in the construction andarrangement of parts will be appreciated from the description to follow,which, for a clear understanding of the invention should be consideredin connection with the accompanying drawings forming a part hereof, andwherein a preferred embodiment of the invention is shown for the purposeof illustration.

In the drawings Figure l is a transverse section through a supportingsill with the improved attachment applied thereon, the same being shownin side elevation;

Bi 2 is a top plan thereof, and

Fig. 3 is a detail in perspective of one of the supporting plates. 7

Similar characters of reference are employed in all of the abovedescribed views to indicate corresponding parts.

Referring now in detail to the several figures of the said drawings, Ihave shown by way of illustration, the locking attachment as applied toa support ng sill 1, whichsill may be used in conjunction with asleeping porch or a window frame. However, in this connection it is tobe noted that the device may be equally well adapted for use uponvarious constructions where it is de sirable to provide an awning, shadeor screen locking means. A plurality of horizontally alined openings 2are formed within the depending portions of the sill 1 and have arrangedadjacent thereto guiding or supporting plates 3, the said plates beingsecured in position, by means of screws or other suitable fasteningdevices which are passed through openings, generally indicatedby thenumeral 4 in the plates. Rectang'ular openings 5 are formedsubstantially centrally of the plates 3, in angularly disposed relation,the purpose of which will be subsequently apparent.

Referring now to the locking means,

whereby a stay bar 6 of the awning 7 will be retained in a fixedposition, there is provided an arm 8, the said arm being twistedintermediate its length, as at 9 and provided with a hooked portion 10.The forward portion ofthe arm is passed through the vertically arrangedopening 5 in the plate 3, wh le the outer or rear portion thereof isslidably engaged with the horizontally positioned opening in theremaining plate 3. A series of openings 11 are arranged'within theforward part of thearm 8 and afford means whereby the locking element,which will be presently described, can be adjustably engaged therewith.

With a view toward providing an eflicient locking element, an arm 12having a plurality of spaced apart openings 13 formed therein, isemployed. The forward end of the arm is bent or curved upon itself toprovide a cam surface 14, which surface is adapted to be engaged withthe adjacent face of the sill 1, when it is desired to move the arm 8into locked position. A bolt 15 is passed through certain of theopenings formed in the arm 12 and also through one of the openings inthe arm 8, whereupon a locking nut 15' is turned into engagementtherewith and the two elements thus, efficiently connected,

The operation of the attachment may be reviewed as follows: v Theawning? when in unrolled" or lowered position has the stay bar 6 thereofengaged by the hooked portion 10 of the arm 8,Twhereupon the :outer'endof the arm '12 is swung downwardly, causingthe cam surface thereof to beengaged with the ad arent face of the sill 1, which actioni will asupport, an arm projecting from said supcause the lower portion of .theawning to be drawn inwardly by the arm 8 and locked 1n fixed position,when the said outer end of thearm' 12 hashesm ed to i s lo e mosPQSILUQB, h w hen the m rfa e a afierded .byp lie cu ed po t 4 Posi- .tiely eng with hesill l Ob iou y,

-al of the s me, wil b Pre nt n erefore, any attempts which might bemade to gainlentrance at this point will be defeated .Nhilel have hereinillustrated and de- ;scribed with a considerable degree of particularity, constructional details of the device el ibodying myinvention, I do not wish to be understood as confiningathe invention tothe-particular form shown, nor to the .eX- act construction, arrangementand adaptation of the parts shown and described, but I reserve the'righ-tto make any changes and alterations that fairly vfall within thespirit and scopeof the invention.

\Vhat is claimed is:

1 .v In an awning lock, the combination of port,said arm terminating ina hooked portion, said hooked portion projecting toward said support,said hooked portion being adapted to receive the bar .of an awning andengage said support for holding said arm in adju d s t Position- .3. vIn an awning lock, the combination of a-supp tr n a sl a ly eunted th ncopies- 2: he p in; ma e ain {or and projecting thereon its outersurface, said arm terminating in a hooked portion extending toward saidsupport, said arm having openings formed adjacent its inner end, asecond arm having a cam formed thereon, pivot means passlng through saidlast mentioned arm and one of the openings in the first mentioned arm,whereby said last mentioned arm may be swung, thereby causing said careto draw upon said first mentioned arm for moving said hooked portiontoward said support, whereby an awninglbar carried by said hookedportion may beheld in set position.

it. In'an awning lock, the combination of an arm formed from a flatpiece of material and twisted intermediate its ends, the outer end ofsaid arm terminating in a hooked portion, a flat arm pivotally mountedupon the other end of said first mentioned arm, a cam formed upon saidlast mentioned arm, whereby as said last mentioned arm is s ung, saidcam will cause said last mentioned arm to draw upon said first mentionedarm, thereby holding an awning bar, which may be carried by said hookedportion in set position.

5. In an awning lock, the combination of a support having openingsformed there- .through, plates fixedly mounted upon said openings andhaving rectangular openings formed therein, said openings extending atright angles to each other, an arm formed from a flat strip of materialtwisted intermediate its ends and extending through said openings,whereby said plates will steady said arm, said arm having a hooked outerend, said hooked outer end being adapted to receive an awning bar, anarm pivotally mounted upon the inner end of said first mentioned arm,said last mentioned arm having a cam formed thereon, whereby when saidlast mentioned arm is swung, it will draw upon said first mentioned armfor retaining said hooked portion in an adjusted set position.

In testimony whereof I allix my signature in presence of two witnesses.
